Wavefront Sensors: Adaptive Optics

Scientific paper

It is shown that the error propagation problem associated with curvature
sensing can be offset when the sensor is used in a closed feedback loop
with an unresolved reference point source. A demonstration is given in
the ideal case of full compensation under low noise conditions.
